- Microsoft.

- >If it's multitasking, is it preemptive or non-preemptive?
-
- Depends. It does preemptive multitasking in Enhanced mode between the
- single Windows environment and each DOS box. It does cooperative
- event-driven multitasking between Windows applications in the single
- Windows environment (which is meanwhile being merrily preemptivvely
- multitasked with any DOS programs you have running).
-
- >Are DOS and Windows applications processed in a diferent way? How?
-
- Yep. DOS applications are preemptively multitasked. Windows
- applications are cooperatively multitasked using an event-driven
- paradigm.

- >What are the main differences between Win 3.x and the forthcoming Win NT?
-
- Win 3.x exists and runs this year. :-)
